Fans hoping for regular tweets coming from the fantasy writer himself (@GRRMspeaking) might be disappointed. Martin, who recently revealed that he still uses a DOS machine to write his novels, pointed readers back to his blog in his first tweet, explicitly designating the purpose of his Twitter account: “Essentially my minions will be using it to echo news and comments from my Not A Blog.”
